    • Diet Data from Fecal DNA Metabarcoding and Video Camera Collars from the Porcupine Caribou Herd, Alaska and Yukon

    Metadata Updated: January 6, 2026

    These diet data were collected from the Porcupine caribou herd in northern Alaska and Yukon in summer 2021 during 4 periods: calving (occasion 1), post-calving (occasion 2), mosquito harassment (occasion 3), and mid-summer (occasion 4). Diet data was determined by two distinct techniques: DNA metabarcoding data from fecal pellets and video data from camera collars deployed on adult females. We provide five tables: (1) the raw number of reads/exact sequence variant (ESV) from the metabarcoding laboratory, (2,3) the relative read abundance from sequences with >90% DNA match to known plant and fungi taxa, (4) the raw forage data detected in 9-second videos, and (5) summarized video forage data.
